You should replace them in a set.

I have a Plasma TV with black screen and 6 red light flashes.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

My usb overheated and now wont light up and let me see my files


This is WORKED FOR ME!--->I turned off my computer than unplugged cable and took out battery, held down power button for 1-2mins and than put everything back in (battery and charger) and tried to start it...the screen was still black. I than turned it off again, than pressed ESC, while holding down ESC I pressed and held power button until it briefly turned on and back off. Than I let go of both the buttons and pressed power back on and VOILA the screen came back on. Make sure your charger isn't loose, and than you're aren't surging too much power through the outlets-sometimes these can make the screen black too.
Hope this helps others out there, I have an old Toshiba Satellite running on Windows Vista

Flash not working, but every thing an the flash is working


Have you perhaps set the flash to remote mode by error. Have a look at the back screen when its turned on, if it says remote you must hold the sel button for a few seconds, press it again briefly then scroll up to the off position, your turning off the remote activation, not the flash when yo do that.

Samsung Sync Master 943bw monitor shuts down after a few minutes, behaves as though it is overheating, will only flash briefly if attempted to open immediately. starts again after standing for some...


Mine shut down during my normal working day. Same thing, turn it off and on again - screen flashes up briefly then flicks off again.
Called Samsung and they are replacing it with a refurbished screen under warranty.
